Mine was set at 10 and has been since around 2003 so I was kicking around having it upped some. When I got coronavirus I googled how to change the pressure on my model and jumped it up to 12. I told my doctor at my last checkup and he started laughing and told the nurse I modified my Cpap. Then he went on to say how smart that was.
